Popular questions
What is tannin in wine?
Tannins are natural polyphenols from grape skins, seeds, stems, and oak that give wine its mouth-drying astringency and structure, helping stabilize color and support aging.
What is a tannin?
A tannin is a plant-derived polyphenolic compound (E181) that binds proteins and other molecules, causing astringency and sometimes used in foods for color and stabilization.
What is tannin bleed?
Tannin bleed is yellow-brown staining that occurs when water‑soluble tannins migrate from wood through paint or coatings; it’s minimized with stain‑blocking primers and proper sealing.
What is tannin in tea?
In tea, “tannins” are polyphenols (such as catechins and theaflavins) that cause bitterness and a puckering, astringent feel, which intensifies with longer steeping.
What is a tannin in wine?
In wine, tannins are grape- and oak-derived polyphenols that contribute bitterness and a drying mouthfeel while adding structure and age‑worthiness.
Is crospovidone safe for dogs?
Generally yes—crospovidone is an inert, non‑absorbed excipient used in veterinary medicines and small amounts are considered low risk; for dosing or if a large amount was ingested, consult a veterinarian.
Is crospovidone gluten free?
Yes. It’s a synthetic polymer and not derived from wheat or other gluten-containing grains, so it’s considered gluten‑free.
Is crospovidone safe?
Yes—E1202 (PVPP/crospovidone) is authorized for use in foods and beverages, and evaluations by bodies like EFSA/JECFA found no safety concern at permitted levels; it is insoluble and not absorbed.
Is crospovidone vegan?
Yes. It’s a synthetic, petroleum‑derived polymer with no animal ingredients and is often used as a vegan-friendly fining agent in beer and wine.
Is crospovidone formaldehyde?
No. Crospovidone is a cross‑linked polymer of N‑vinylpyrrolidone, not formaldehyde, and food/pharma grades have tight limits on residual monomers and impurities.
